Title: Non-repudiation cross-chain transaction method and blockchain system
Inventor: DONGYUN LI
IPC: H04L9/32
Filed: 2020-09-29
Granted: 2021-12-01
Abstract: A non-repudiation cross-chain transaction method and a blockchain system are provided. The method includes: creating a cross-chain transaction by a public chain; forwarding, by an initiating parallel chain, a ﬁrst locking request to a transaction initiating chain; performing, by the transaction initiating chain, a service transaction based on the ﬁrst locking request, and locking transaction content of the service transaction; forwarding, by a target parallel chain, a second locking request to a transaction target chain; performing, by the transaction target chain, the returning transaction based on the second locking request, and locking transaction content of the returning transaction; and when it is determined that both the service transaction and the returning transaction have been performed, instructing, by the public chain, the transaction initiating chain to unlock the transaction content of the service transaction, and instructing the transaction target chain to unlock the transaction content of the returning transaction. In the present application, the public chain instructs the transaction initiating chain and the transaction target chain to lock and unlock respective transaction contents, respectively, when the transactions are performed by both parties . In this way, it is possible to avoid losses of the other party caused by that one party does not perform the transaction, thus achieving non-repudiation effects, thereby ensuring that the cross- chain transaction can be safely completed.

Title: Exhauster for pneumatic seed drill and other machines and instalations
Inventor: NEACSU MIHAIL FLORIAN-NICOLAE
IPC: A01C7/16
Filed: 1996-12-09
Abstract: The invention refers to a blast-spout for pneumatic seed drill machines and other machines or installations in which, in order to simplify the design and increase its operating safety, the rotor has blades (5) which are mounted in between two disks with elongated holes, by using the hooks (a) on the blades, without any other assembling elements, which retains the disks in a stack. After the hooks of the blades are inserted in the elongated holes of the two disks, the blades are pushed so that they fix the stack, and are maintained in this position by a disk (8) which prevents their displacement, or by local deformation of one of the walls of the rotor. The negative pressure is adjusted by absorbing air from the atmosphere through an adjustable section slot located on an element that ensures connection with the chamber in which negative pressure is created. A piece (9), which is made up of one or more tapered surfaces connected to each other, contains the elements for assembling the rotor body to the axle, and prevents displacement of the blades.

Title: Imprimante dotee d'une meilleure qualite de police
Inventor: NYE ANDREW B III
IPC: G06K15/02
Filed: 2001-12-06
Abstract: L'invention concerne une imprimante ayant la capacité d'imprimer sur des supports thermiques bichromes et fournissant des caractères noir foncé. En raison de leur chimie, les supports bichromies produisent un « effet de halo » autour des caractères noirs, ce qui diminue la netteté et les font apparaître « délavés ». L'imprimante de cette invention a un contrôleur qui dicte que les caractères imprimés sur différents supports (par exemple sur des supports monochromes ou bichromies) doivent comporter un ensemble de caractères en mode points différent. L'ensemble en mode points utilisé pour des impressions bichromes fournit des caractères ayant une largeur de trait plus épaisse, et par conséquent ces caractères donnent l'impression d'être plus noirs. Cette apparence plus noire contrebalance la diminution de netteté des caractères due à « l'effet de halo ».
